| We use a monitoring tool that has the automated checks for the
application

able

| have the check run by the load balancer know that the system is down
--
| and
| it does only a simple check against this JSP page, and then knows to
fail
| over -- so while we are working to establish threshhold alerts with
our
| monitoring application, we also want to ensure the load balancer fails
| over
| accurately as well...
| 
| So all suggestions are welcome.

I'm not entirely sure how feasible this is, but can you have an output
filter or valve catch (or at least note) the 500 status?  If so, then
maybe it could log an error to the database.  Since you said your status
page was able to hit the database even after the app crashed, you should
hopefully be able to retrieve the error indication.
